GITLAB-1457 (GITLAB-836)

Change-Id: If8e2474bc6908accca51f395f58937687f101b58

Fix error described in https://github.com/gitlabhq/gitlabhq/issues/5185

Labels are saved in the database with the case they were originally created with.
Before this change if a user created a label with the same text but different case
the label would use the original case and no new label would be created in the
database. With this change, labels are now case-sensitive.

Steps to test:

1. Before this change, create a new issue with a new label "FIxMe"
2. Edit the issue and change the label to "FixMe"
3. Note that the label reverted to "FIxMe"
4. Apply this change
5. Edit the issue again and change the label to "FixMe"
Note that the new case was preserved. If you also look in the database in the "tags" table you will see that both labels are present - "FIxMe" and "FixMe".

Added test for the FlowdockService.

Before we have only owner_id to determine group owner
With multiple owners per group we should get rid of owner_id in group.
So from now @group.owner will always be nil but
@group.owners return an actual array of users who can admin this group

So lets do it async. First create project, then import repo and create
satellite with Sidekiq

The good:

 - You can do a merge request for a forked commit and it will merge properly (i.e. it does work).
 - Push events take into account merge requests on forked projects
 - Tests around merge_actions now present, spinach, and other rspec tests
 - Satellites now clean themselves up rather then recreate

The questionable:

 - Events only know about target projects
 - Project's merge requests only hold on to MR's where they are the target
 - All operations performed in the satellite

The bad:

  -  Duplication between project's repositories and satellites (e.g. commits_between)

(for reference: http://feedback.gitlab.com/forums/176466-general/suggestions/3456722-merge-requests-between-projects-repos)

Fixes:

Make test repos/satellites only create when needed
-Spinach/Rspec now only initialize test directory, and setup stubs (things that are relatively cheap)
-project_with_code, source_project_with_code, and target_project_with_code now create/destroy their repos individually
-fixed remote removal
-How to merge renders properly
-Update emails to show project/branches
-Edit MR doesn't set target branch
-Fix some failures on editing/creating merge requests, added a test
-Added back a test around merge request observer
-Clean up project_transfer_spec, Remove duplicate enable/disable observers
-Ensure satellite lock files are cleaned up, Attempted to add some testing around these as well
-Signifant speed ups for tests
-Update formatting ordering in notes_on_merge_requests
-Remove wiki schema update
Fixes for search/search results
-Search results was using by_project for a list of projects, updated this to use in_projects
-updated search results to reference the correct (target) project
-udpated search results to print both sides of the merge request
